FEED-"CUP FO'R FERTI L'rzE'R- DI'STRIBUTERS.

SPECIFICATION forming part of Letters Patent No. 236,900, dated January25, 1881.

Applicationfiled December 9, 1879.

To all whom it may concern:

Be it known that I, WALTER MARKS, of Ohapinville, Ontario county, NewYork, have invented certain Improvements in Feed-Cups forFertilizer-Distributers, of which the following is aspecification,reference being had to the at iexed drawings,-in which-Figure 1 is a plan view of my improved feed-cup forfertilizer-distributers. Fig. 2 is a view of the same as seen frombeneath. Fig. 3 is a central vertical section of the sanie. Fig. 4. is aside view of the feeding-shell. Fig. 5 represents a modification of thesame. Fig. 6 is an inverted view of the feeding-shell. Fig. 7 is apartial side elevation of the feedingshell. Fig. 8 is a plan view ofaportion of the supporting-frame. Fig. 9 shows'the mode of attaching thedistributer to the inside of the feed-cup. Fig. 10 is a section throughthe cleaner.

My invention relates to certain improvements on the feed-cup forfertilizer-distributers patented July 15, 1879, No. 217 ,628; and itconsists in attaching the feeding-shell to the supporting-frame so thatit may be readily removed therefrom.

My invention also consists in an improved form of the feeding-shell andin an improved clearer for preventing the fertilizer from adhering tothe same.

My improvements in feed-cups for fertilizerdistributers are representedin the accompanying drawings, in which A is the feed-cup, which isprovided on its lower side with a bevel-gear, B, meshing with a pinion,(shown in dotted lines,'G, Fig. 3,) by which the cup is rotated. 'D isthe feeding-shell, which is provided with a projecting lip, E. Thebottom of the feed-cup is provided with an opening of the same size asthe interior of the feeding-shell, which opening is crossed by radialarms. (Sh, owfrin dotted lines at b b b, Fig. 1.) The radial ar'ms b b bare connected with a central ring, .0, Fig. 3, by which the feedcup isheld in position on a hub, 01, which projects upward from\ thesupporting-frame N. By means of this hub the feed-cup is held'in placeon the'supporting-frame when the feedingshell D is removed. The feed-cuprotates in the direction shown by the arrows in Fig. 1, and thefertilizer in the cup, by the combined action of the distributing-rod Fand the feedcup, is forced into the opening in the projecting lip' ofthe feeding-shell, from which it passes through the opening 6 in thesupporting-plate.

In order'to remove the feeding-shell through the feed-cup thedistributing-rod F must first be taken out. This I accomplish byfitting-one end of it into a hole in the side of the feed-cup and theother end into a right-angled slot, 1', Fig. 9, on the opposite side ofthe feed-cup. The end of the rodis passed downward through the verticalportion of the slot f, and is then moved sidewise until it bears againstthe end of the slot. The pressure of the fertilizer against thedistributing-rod, when in rotation, holds it in place in the slot.

The feeding-shell D may be made removable from the supporting-frame indifferent ways, in each of which the shell is locked to the frame byinserting a lug into a recess and rotating the shell until it comesagainst a stop, in a manner substantially similar to that alreadydescribed with regard to the distributing-rod F. The shell beingarranged to turn in the same direction in which the feed-cup revolves,the friction on the shell will keep the same locked to thesupporting-frame. In the accompanying drawings I have'represented'one-mode of accomplishing this result, in which the feeding-shell isprovided with a central hub orboss, g, which passes downward through thesupporting-frame, and is provided with a lug or lugs or pin, 6 'i, whichpass through slots 01. n, Fig. 8, in the sides of the opening in theframe when the hub is inserted therein, and which pin, bearing againstthe projections o 0 on the supporting frame, prevents the furtherrotation of the feeding-shell. The surface .of the supporting-framebetween the slot n and the stop 0 may be given an inclined orscrewthreaded form, in order to secure the feedingshell firmly to thesupporting-frame. This arrangement may be reversed, the hub being placedon the supporting -frame, passing through an opening in thefeeding-shell. In this case a recess should be made on the top of thefeeding-shell to receive the pin 1', so as not to interfere with therotation of the distributer F, immediately above the feedingshell; or aright-angled recess for the pint may be formed on the inside of theopening into which the hub is inserted, whether the hub be placed on theframe or the shell.

In order to keep the opening into the feeding shell clear, I make theedge of the projecting lip E of the top plate of the shell with aninclination in the direction of the rotation of the feed-cup, as shownin the drawings. This edge is sharpened by being beveled from the insideof the shell. The edge of the flange 1), Fig. 7, which extends downwardfrom the projecting lip, at the outside thereof, is also given aninclination in the same direction. It is also sharpened from the inside.The distributer F is so placed that in its revolution it will just clearthe projecting lip E, which is elevated slightly above the surface ofthe feeding-shell. By this means any hairs or other fibers, such as arefrequently found in commercial fertilizers, are prevented from catchingon the edge of the lip and thus clogging the feeding operation.

In order to clear the corner between the lip and the flange p, ahorizontal slot, r, Fig. 7, is made in the flange, and a cleaner, 1], issecured to the feed-cup in such position that in rotating it will passthrough the slot 1.

The cleaner ll may be riveted to the feedeup, and its forward edgeshould be sharpened from its lower side, as represented in the sectionalview, Fig. 3. The cleaner II is preferably inclined backward from thedirection of rotation of the feed-cup, as represented in Fig. 6. It maybe inserted in any part of the feedcup, and two or more of thesecleaners may, if desired, be used.

Fig. 5 is a plan view of a modification ot' the feedingshell, the shellitself being shown in that figure in horizontal section below its topplate. An opening, I, in the side of the feeding-shell is substitutedfor the projecting lip, and a row of inclined feeders, L L L, attachedto the rotating feed-cup, is arranged to feed the fertilizer into thesaid opening. Any desired number ofthese feeders may be employed atsuitable distances apart. They may be either cast with the feed-cup orsecured thereto in any convenient manner, and they should be inclinedbackward from the radius of the feed-cup, as shown in the figure. Thefeeders L L may also be employed with the projecting lip E if space beleft for their rotation between the outer margin thereof and theinterior of the feed-cup for their rotation.

The feeding-shell may be made with its top of a spherical form, eitherwith or without the projecting lip. In this case the distrihuter F wouldbe modified in form to correspond with the change in the feeding-shell.

The cleaner 11 serves to prevent the fertilizer from adhering to theunder side of the projecting lip. The outer corner of the projecting lipextends beyond the top ot'the flange p, as shown in Fig. 7.

I claim- 1. The frame or bed N, provided with a hollow hub, combinedwith a rotating cup and hopper, and within said cup the feeder 1),provided with a stud,g, and pin or pins ii, which are adapted to passdown through said hollow hub and be locked below said bed by apartialrotation of said feeder and stud, whereby said bed, cup, and feeder areunited and held in place without employing anydetachablc bolts or keys.

2. The revolving cup and hopper, combined with the stationaryscroll-shaped feeder having a scroll-flange continuous from end to end,as described.

3. The bed or frame N, upon which the revolvin g cup is centered,provided with the hanging bracket-bearing, in the flanges of which arelongitudinal slots to receive and keep in place the hubs of thedriving-pinion, substantially as described.

4. The combination of the feed-cup A, feeding-shell 1), havingprojecting lip E, with slot 1 at its upper corner, and the cleaner H,adapted to tit the slot r, the whole constructed and operatingsubstantially as set forth.
